Abstract

The cardiac activity of the hexane, chloroform, methanol and water extracts from O. limnetica, H. reticulatum and M. lacustris were investigated in isolated heart preparations in Wistar rats. The bolus injections of hexane extract from O. limnetica, water extract of H. reticulatum and chloroform extract from M. lacustris produced significant coronary dilator action and a protective effect against reperfusion-arrhythmias in the isolated and perfused rat heart. M. lacustris is more active than O. limnetica and H. reticulatum. These algae possess significant antianginal and antiarrhythmic properties.
